SPECHPICATION forming part of Letters Patent No. 335,829, dated February9, 1886.

I Application filed November 4, 1885 Serial No. 181.852. (No model.)

To aZZ whom it may concern:

Be it known that we, WILLIAM MOORE and J oHNB. CARTER, of Kokomo, inthecounty of Howard and State of Indiana, have invented certain new anduseful Improvements in Ventilators for Houses; and we do hereby declarethe following to be a full, clear, and exact description oftheinvention,such as will enable others skilled in the art to which it pertains tomake and use it, reference being had to the accompanying drawings, whichform part of this specification.

Our invention relates to an improvement in ventilation for houses; andit consists in a suitable opening made through the ceiling or floorbetween the upper and lower rooms, a suitable metallic fra1ne,which isplaced therein, a disk-valve for closing the opening,a guide upon whichthe valve moves, and a lever or other means for opening and closing thevalve either from the room below or the one above, as will be more fullydescribed hereinafter.

The object of our invention is to place a ventilator in the top of aroom around the stovepipe, or simply in the floor between an upper andlower room, and in which ventilator a dislevalve is used, and which canbe opened from either above or below, for the purpose of allowing thewarm air in the upper part of the room either .to escape through a lineor to pass into the room above.

Figure 1 is a vertical section showing our invention applied to astove-pipe. Fig. 2 isa similar view showing our invention placed betweenan upper and a lower room.

'A represents a stove-pipe, which is placed inside of the sheetnietalflue B. The lower end of this stove-pipe passes down into the top of theroom, and to which lower end of the stove-pipe are attached the othersections of the pipe which lead directly from the stove. This stovepipebeing smaller than the flue, asuitable space is-left between the two forthe free escape of the heated air in the room between them when thevalveC is open. The lower end of the flue rests upon the top of the ironcasting D, which is made concave upon its under side,so as to form afunnel-shaped guide, into The diskvalve 0 is made of a shape tocorrespond to the concave portion D, so that when moved up against thepart D the space between the stove-pipe and the flue will be tightlyclosed, and thus prevent any escape of air from the room. Thisdisk-valve G has an opening through its center, where it passes over thelower end of the stove-pipe A, so as to be guided vertically in itsmovements. Formed upon the top edge of this dislr-valve is a flange, G,which projects upward around the stovepipe any suitable distance, and tothe upper edge of this flange is loosely connected theinner pronged endof the lever H. To the outer end of this lever H is connected the rod I,which passes down through the opening made in the ceiling, and throughthe edge of the e11- larged part I) into the room, where it can bereadily reached at any time desired. Bypulling down upon this rod H thedisk-valve is made to close, so as to prevent any of the heat ed air inthe upper portion of the room from escaping therefrom, and when this rodH is forced upward the valve is forced downward, so as to open the spacebetween the stove-pipe and the flue, and thus allow the heated air tofreely escape.

When it is desired to place a ventilatorin a floor between an upper anda lower room, the flue and the stove-pipe are dispensed with and agrate, O, is placed over the opening which is made in the floor, andfrom the center of this grate there is made to project down ward aguide, J, which acts in the same manner and for the same purpose as thestove-pipe to the dislcvalve. The lever may besupported from a suitablehanger which is formed on the under side of the grate and connected tothe dislevalve, as shown, or in any otherway that may be preferred. Whenthe rod and lever are moved so as to open the valve, the heated air inthe lower room passes upward into the upper one as from a register; butwhen the disk-valve is closed there is no communication whatever betweenthe two rooms so far as this ventilator is concerned.

Having thus described our invention, we claim- 1. In a ventilator forhouses, the ceiling or the floor between the rooms provided with anopening, the perforated metallic casting D, which is placed in theopening, the disk-valve located in the lower end ofthe opening andacting in conjunction with the casting, the guide upon which thedisk-valve moves, and a mechanism for moving the valve, whereby it canbe closed from the lower room, the parts being combined substantially asshown.

2. In a ventilator for houses, the ceiling or the floor between tworoomsprovided with an opening, the perforated metallic frame D, which isplaced therein,andadisk-valve placed in the lower end of the openingbeneath the frame D, and which is moved vertically for the purpose ofopening and closing the opening in the floor, the parts being combinedto operate as described.

3. In a ventilator for houses, the flue D, placed in an opening betweentwo rooms, the

grating O, the guide J, connected thereto, the valve 0, provided withthe flange and moving upon said guide, the lever for moving the valve,and the rod connected to the lever, the parts being combined to operatesubstantially as specified.

In testimony whereof weaffix oursignatures in the presence of twowitnesses.

WILLIAM MOORE. JOHN B. CARTER.
